Why do private insurers closely link their physician payment rates to the Medicare fee schedule despite its well-known limitations? We ask to what extent this relationship reflects the use of Medicare's relative price menu as a benchmark, in order to reduce transaction costs in a complex pricing...

The long-run costs and benefits of social insurance expansions may not be realized until a program has been in place through a cycle of boom, bust, and recovery. In the case of the Affordable Care Act (ACA), the arrival of the program's inaugural bust and recovery have been hastened by the...

Proposals to create a national health care plan such as "Medicare for All" rely heavily on reducing the prices that insurers pay for health care. These changes affect physicians' short-run incentives for care provision and may also change health care providers' incentives to invest in capacity,...
